Self-Checking Concurrent Error Detection System Design Based on Boolean Complement Method to “1 out of 3” Code with Hardware Cost Optimization

Abstract

The authors of the article developed a new approach to organizing concurrent error detection of logical devices of automatics and computing machinery based on the method of Boolean complement to “one out of three” constant-weight code. The introduced approach gives freedom of choice of testing equipment architecture in contrast to the established approaches. The example of managing a concurrent error detection system was studied in the article. It is based on step-by-step shipping of values of test functions taking into account testability of XOR elements and a checker with the introduction of uncertainties for the purpose of complexity optimization of the functions. The method in question is multipurpose and makes it possible to solve the task of building a concurrent error detection system with a totally self-checking structure in all cases.
